How to Vacuum Your Inground Pool
How to vacuum your ingorund or on-ground pool from Pool Builders
*POOL PUMP MUST BE ON DURING ENTIRE PROCEDURE
Take out your vacuum pole, hose, skimmer adapter, and vacuum head.
Connect one end of the hose to the vacuum head (the hose end that is the most snug is the proper end for the vacuum head). Connect the other end of the hose to the skimmer adapter. Connect your vacuum pole to the vacuum head.
Prime your hose. Leave the skimmer adapter (connected to one end of the hose) on the deck, and plunge the vacuum head (connected to the pole) in the pool. Hold the vacuum head on one of the returns (jets) to fill the hose with water. Once water starts flowing out of the skimmer adapter end, leave the vacuum head under water and place the adapter in the skimmer. Suction of the pump will hold the adapter in place.
Go to your 3 way valve at the pool pump. Coming from the pool there are 2 lines, 1 Main drain, and 1 Skimmer. Shut off the main drain so that you are only drawing water from the skimmer. * If you notice your pump is drawing a lot of air at this point, simply open the main drain half way.
Vacuum your pool. You may vacuum anything that is under water. Keep in mind this vacuum is much slower than a normal home vacuum. Go over the debris slowly.
Once you are done vacuuming, simply turn off your skimmer line (open the main drains only) using your 3 way valve at the pump. Take out the skimmer adapter from the skimmer, drain and roll up your hose. Return your 3 way valve to normal operation (in the middle drawing from both main drain and skimmer).
